Abstract
The utility model provides a protection head cover used for an anti-gas mask. The protection head cover is of an integrated structure, the front of the head cover is provided with an opening, the edge of the opening is provided with an elastic band, the opening is matched with the edge of the anti-gas mask in shape, and the head cover is a composite woven fabric body of a three-layer structure including an outer aramid fiber woven fabric layer, a middle activated carbon fiber woven fabric layer and an inner non-woven fabric layer. In terms of the three-layer structure of the head cover, the aramid fiber woven fabric layer on the outermost layer has a permanent flame-retardant effect and high breakage strength, the surface of the aramid fiber woven fabric layer undergoes waterproof and oil-proof finish, and large toxic liquid drops can be prevented from seeping into the aramid fiber woven fabric layer; the middle activated carbon fiber woven fabric layer has excellent poison gas absorption performance, high tensile failure strength, high tensile elongation at break and good gas permeability and is non-combustible when touching a fire; the inner light and thin non-woven fabric layer cannot increase heat load of the head cover, and meanwhile, the activated carbon fiber woven fabric in the middle layer can be effectively protected.
Description
Technical field
The utility model relates to a kind of Protective clothes combined with cap and mask, be specially one can with the matching used Protective clothes combined with cap and mask of breathing mask, be mainly used in the skin protection under the raw environment of coring.
Background technology
Existing breathing mask supports the use with band cap frog suit, bulletproof halmet conventionally, exists in use frog suit and breathing mask adaptation poor, and frog suit and bulletproof halmet matching are poor, the inconvenience of execution tactical operation, frog suit guard time is short, intensity difference, the problems such as poor fire.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Protective clothes combined with cap and mask for breathing mask, the gas defence of can preventing fires, and intensity is high, good with breathing mask and bulletproof halmet matching.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Protective clothes combined with cap and mask for breathing mask, this Protective clothes combined with cap and mask is integral type structure, the front of head-shield is provided with opening, the edge of opening is provided with elastic force elastic cord, and the shape of opening matches with the shape at breathing mask edge; Described head-shield is the compound fabric body with three-decker, is outer field kevlar fabric layer, the NACF tissue layer of centre and the nonwoven layer of internal layer.
The thickness of described kevlar fabric layer is 0.22 ~ 0.33mm; This gauge can not affect wearing of the helmet, can ensure the mechanical property of kevlar fabric simultaneously, kevlar fabric layer has permanent fire retardant effect, high ultimate strength and high tearing brute force, kevlar fabric surface adopts fluorine-containing dressing liquid to carry out water and oil repellent finish, grease proofing grade is not less than 6 grades, can prevent the infiltration of the large drop of toxic agent.
The thickness of described NACF tissue layer is 0.5 ~ 0.6mm; This gauge can not affect wearing of the helmet, can ensure that active carbon fibre dimensional fabric has mechanical property and the absorption property of instructions for use simultaneously.The middle level of this Protective clothes combined with cap and mask arranges NACF tissue layer, makes Protective clothes combined with cap and mask have superior poison gas absorption property,, and the gas permeability of this layer is good, meets fire and does not fire.
The thickness of described nonwoven layer is 0.08 ~ 0.1mm; Because nonwoven layer has the features such as ventilative, pliable and tough, light weight, nontoxic nonirritant; set it as the internal layer of this Protective clothes combined with cap and mask; itself and head and neck are fitted; lightweight is comfortable; can not increase the thermic load of Protective clothes combined with cap and mask; can coordinate with NACF tissue layer, effectively prolection carbon fabric layer, increases its anti-wear performance and washing fastness simultaneously.
The opening of this Protective clothes combined with cap and mask adopts elastic force elastic cord to regulate, and the girth adjustable range of elastic force elastic cord is 50 ~ 70cm.This opening part can be coordinated with the breathing mask of different model, and by the elastic force elastic cord of opening, mask and Protective clothes combined with cap and mask are fitted tightly, there is good sealing property, guarantee to use safety.
The distance of described head-shield from top center to bottom margin is 35 ~ 45cm; Because head-shield has certain length, this Protective clothes combined with cap and mask can be coordinated with upper garment, cover staff's neck and shoulder, effectively isolate the disadvantageous external environments such as poison gas.
The beneficial effect the utlity model has is:
1) Protective clothes combined with cap and mask of this practical setting, quality is frivolous, dresses comfortablely, after staff wears breathing mask, upper this Protective clothes combined with cap and mask of cover, can effectively isolate external environment, prevents that skin of head is exposed in external environment, ensures carrying out smoothly of work.
2) compare traditional band cap frog suit, the stickiness of itself and breathing mask and the helmet is better, structural design is more reasonable, and staff is more convenient in the time carrying out tactical operation.
3) interior, the domestic and abroad three-decker design that the compound fabric of Protective clothes combined with cap and mask adopts, can effectively shield external environment, guarantee staff's safety, this Protective clothes combined with cap and mask skin has good wearability, fire resistance, the protection time of Protective clothes combined with cap and mask enemy, neck can be improved in intermediate layer, internal layer makes to dress comfortable, and three-decker cooperatively interacts, and Protective clothes combined with cap and mask can effectively be protected.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of head-shield material.
Detailed description of the invention
As Figure 1-Figure 2, head-shield 1 of the present utility model is integrated, the front openings 2 of head-shield 1, and the edge of opening is provided with elastic force elastic cord 3, and the shape of opening matches with the shape at breathing mask edge; Described head-shield 1, for having the compound fabric body of three-decker, is outer field kevlar fabric layer 4, the NACF tissue layer 5 of centre and the nonwoven layer 6 of internal layer.
The thickness of described kevlar fabric layer 4 is 0.22 ~ 0.33mm, and the thickness of NACF tissue layer 5 is 0.5 ~ 0.6mm.The thickness of nonwoven layer 6 is 0.08 ~ 0.1mm.The opening 2 of this Protective clothes combined with cap and mask adopts degree of tightness to regulate, and opening girth is adjustable to 50 ~ 70cm, and the length of head-shield 1 is 35 ~ 45cm.Because head-shield has certain length, this Protective clothes combined with cap and mask can be coordinated with upper garment, effectively isolate the disadvantageous external environments such as poison gas.
